During this clip I solder pins to a board. I also attach the board to the LED strip. Both these steps were done incorrectly. So this clip shows where I make two critical errors which come back to haunt me later. They are:

My soldering job is inadequate to the point where it renders the board completely inoperable. I just didn’t get it right. Plain and simple. Later, Karen will notice this after we have done some trouble shooting. It ends up being easily corrected. But it marks an important juncture in my learning journey.

The directionality of the current through the belt is backwards. The coding instructs the board what to send into the belt to make the LED’s do what they are coded to do. There is a direction through which they must go. They must enter through the ends marked CI and DI. Those I’s stand for inputs. I was able to see the C’s and D’s, but the print was so small that I didn’t notice the I’s. Likewise, on the other end of the belt, it says CO and DO. I saw the C’s and D’s but not the O’s. I simply didn’t realize that I was on the wrong end of the belt. Fortunately, this is something pretty easily fixed. Ben helped me realize the error and I fixed it myself. I write more about this at the end of the week.

What I’m doing in this clip is downloading the code to make the belt light up in the pattern that has been designed for it. Eventually, my plan is to alter the lighting pattern and combine it with other components such as sensors (accelerometer or light or sound). During this clip, I first make sure I have the latest Arduino IDE for TeensyDuino. Then I try to get the code for the belt from Adafruit’s GitHub. Since the IDE is open source, my operating system (Mac) wants to make sure that I don’t download something unsafe. So I have to unlock it to allow me to download it.

After briefly reflecting as a large group on our work for the day, we left for MIT Media Lab in the afternoon in a bus. It was lit:

Here is a replica of MIT Media given by the LEGO foundation in honor of their 30th anniversay of collaboration:

The first thing Mitch Resnick did was show us a video.

This gave us some context about the collaboration and how it evolved.
